The U.S. Small Business Administration defines a small business as “an organization with fewer than 500 employees.” The majority of small businesses employ fewer than 100 employees. One and two-person companies make up most small businesses in America. So it’s a very broad definition of “small business.” There’s an enormous difference in running a one-man freelancing operation versus a global 475-person organization yet both would technically be called “small business” based on the SBA’s definition. 
My personal definition is, in some ways, even looser. In other ways, more narrow. I focus on the just a few simple things that I have found more practical for my work in serving CEO’s and business owners. One, it’s got little to do with revenues and head counts. They’re important and there is a correlation between those things and the things I quantify most. How close is the CEO or owner to the generation of revenue? I don’t mean they actually do the selling, but they may help every now and again. How close is the CEO or owner to the actual work of the company? If the company manufactures a product or delivers a service, how involved is the CEO or owner? I consider a business small based mostly on those factors, not on the amount of revenues or the number of employees. My interest is in serving companies that have relatively flat org charts. 
Yes, companies with big revenues tend to have more employees and with that – more layers of management/leadership. However, in the digital age, that’s not necessarily so. For the past couple of decades, a single employee has been armed with sufficient technology to do the work of many. 
According to the SBA 99.7% of American companies are technically “small businesses.” Companies with fewer than 20 employees comprised 89.4% of all businesses. By every standard or measurement, small business dominates the business landscape. It’s been projected that by 2020 about 50% of the workforce will be freelancers. Dan Pink wrote of this in his 2001 book, Free Agent Nation: How Americans New Independent Workers Are Transforming the Way We Live. 
Small businesses may not get the headlines, but they have an enormous impact, both economically and practically. They represent individual and collective power, contribution and potential. This is evidenced by the fact that companies with fewer than 49 employees have been responsible for most of the employment growth, adding 44% of all new jobs. 
Small businesses have long learned the power of the collective. Their size has often compelled them to join forces in buying groups, marketing organization, and other cooperative organization so they can leverage their collective size and power. For example, the Nationwide Marketing Group is in the consumer electronics/home furnishings/major appliances retailing space. Here’s what they say about themselves on their website:
“Nationwide Marketing Group works beside thousands of appliance, furniture, electronics, specialty electronics, custom installation and rent to own dealers helping them grow their businesses and their bottom lines. With some 5,300 members, operating approximately 14,000 storefronts with estimated sales of $18.5 billion, Nationwide is North America’s largest buying and marketing organization. Industry veterans, heading Nationwide’s seven regional divisions, work to provide independent dealers with personalized service and local programming in every market they serve.”
No single member of that organization can possibly be as powerful as they can be together. By working together they’re able to lever...
